Challenger Disaster 30 Years Ago Shocked the World, Changed NASA
By Mike Wall January 28, 2016
https://www.space.com/31760-space-shuttle-challenger-disaster-30-years.html
Thirty years ago today, NASA suffered a spaceflight tragedy that stunned the world
and changed the agency forever.
On Jan. 28, 1986, the space shuttle Challenger exploded just 73 seconds after
blasting off from Florida's Kennedy Space Center, killing all seven astronauts on
board — including New Hampshire educator Christa McAuliffe, a civilian who had
been selected to fly via NASA's "Teacher in Space" program.
NASA astronauts had died on the job before — Apollo 1 crewmembers Ed White,
Gus Grissom and Roger Chaffee were lost when a fire broke out inside their
command module during a launchpad exercise on Jan. 27, 1967 — but the
Challenger disaster was something different altogether. [Remembering Challenger:
NASA's 1st Shuttle Tragedy (Photos)]
"The whole country and the whole world were in shock when that happened,
because that was the first time the United States had actually lost a space vehicle
with crew on board," said former NASA astronaut Leroy Chiao, who flew three space
shuttle missions during his career (in 1994, 1996 and 2000), and also served as
commander of the International Space Station from October 2004 through April
2005.
"It was even more shocking because Christa McAuliffe was not a professional
astronaut," Chiao told Space.com. "If you lose military people during a military
operation, it's sad and it's tragic, but they're professionals doing a job, and that's
kind of the way I look at professional astronauts. But you're taking someone who's
not a professional, and it happened to be that mission that got lost — it added to the
shock."

On Jan. 28, 1986, NASA's space shuttle Challenger exploded after liftoff, killing seven
astronauts and shocking the world. Here's how the Challenger accident occurred.

Before Challenger launched on its ill-fated STS-51L mission, the space shuttle
program had completed 24 missions in a row, starting with the April 1981 liftoff of
the orbiter Columbia. That run of success bred a measure of complacency, Chiao
said.
"There was a 'launch fever' at the time, to try to get these missions off on time, and
get more missions going," he said. That type of thinking played a significant role in
the disaster, experts have concluded. Challenger was lost because a rubber "O-ring"
seal on the shuttle's right-hand solid rocket booster failed, allowing hot gas to
escape and damage the orbiter's external fuel tank, as well as the gear that attached
the booster to the tank.
The O-ring failed in part because unusually cold temperatures on launch day caused

The NASA-contracted Antares cargo rocket, bound for the International Space Station, crashed on Tuesday during liftoff. This is an account of the launch from Pulse Social Media manager Ally Coonradt, an attendee of the event.
NASA cleared the shuttle Endeavour for re-entry and landing after analyzing damage to heat shield tiles from launch. Engineers will evaluate options to modify the external tank to prevent further foam shedding issues. The crew has two opportunities for a Florida landing on Tuesday, with backup options at Edwards AFB if weather delays the return. NASA managers deemed the tile damage does not threaten re-entry and are hopeful it will not significantly impact the upcoming flight schedule.
The document discusses the components and launch process of the Space Shuttle. It summarizes the first Space Shuttle mission flown by Columbia in 1981, which successfully launched and landed, verifying the shuttle system. It also discusses the Challenger disaster in 1986 shortly after launch, as well as the Discovery mission in 1990 which deployed the Hubble Space Telescope. The document notes that Sally Ride was the first American woman in space.
The document summarizes key details about three Space Shuttles - Challenger, Endeavor, and Columbia. It describes how Challenger exploded shortly after launch in 1986 due to an O-ring failure. It details how Endeavor successfully repaired the Hubble Space Telescope in 1993 over five spacewalks. It also outlines how Columbia disintegrated during reentry in 2003 after launch damage to its heat tiles was sustained during liftoff.
The document summarizes NASA's history and key missions from its establishment in 1958 in response to the Soviet launch of Sputnik through the present day. Some of NASA's major accomplishments discussed include the Mercury and Gemini programs, achieving the goal of landing astronauts on the Moon through the Apollo missions, launching and operating the Space Shuttle program, constructing the International Space Station through international collaboration, and ongoing research in aeronautics and areas related to space exploration and Earth science.
STS-134 will be Endeavour's final mission, delivering the Alpha Magnetic Spectrometer and spare parts to the International Space Station. The 14-day mission will feature four spacewalks to install new components and do maintenance work. This is the last scheduled spacewalk for shuttle crew members before the retirement of the Space Shuttle program. STS-134 will deliver the Alpha Magnetic Spectrometer particle physics detector to study the formation of the universe and search for dark matter and antimatter.

The document summarizes three Space Shuttle missions - Columbia STS-1, Discovery STS-31, and Endeavour STS-88. The Columbia STS-1 in 1981 was the first Space Shuttle mission and tested the orbiter, boosters, and fuel tank. It succeeded in launching but had heat shield issues upon landing. Discovery STS-31 in 1990 deployed the Hubble Space Telescope, though it initially sent back blurry images. Endeavour STS-88 in 1998 was the first mission to dock with the Russian Zarya module and help assemble the International Space Station.
Here are definitions for the terms in the context of physics and space exploration:
- Microgravity: The condition of near weightlessness experienced in space. Objects in low-Earth orbit are in a continuous state of free fall which creates a sensation of weightlessness.
- Aeronautics: The science and technology of flight within Earth's atmosphere. It involves the design, development and manufacture of aircraft like airplanes, helicopters, hot air balloons and other flying machines.
- Extra-terrestrial: Originating or occurring outside Earth or its atmosphere. It refers to objects, phenomena and life that are not from Earth but from other celestial bodies like planets, moons, asteroids or other astronomical objects.
2. What is
The document discusses the history and arguments for and against space exploration. It outlines the key events in space exploration history from Sputnik 1 to the first moon landing. Both the dangers and high costs of space travel are presented as counter arguments, while supporting arguments note the technological benefits and spin-offs, curiosity of humankind, and new opportunities space exploration provides. The conclusion recommends that future space systems focus on reducing costs and improving safety, and developing useful technologies to benefit people.

Plans for the space shuttle started in 1970 with the first orbiter, Enterprise, debuting in 1976. Key events included the first American woman, Sally Ride, going to space in 1983, the Challenger explosion in 1986 due to an O-ring failure, and the Columbia disaster in 2003 when heat tiles were damaged on launch. The last space shuttle launch was in 2011, ending the 30-year program.
Shuttle Discovery was the third orbiter built by NASA and has had over 20 years of upgrades and experience. It has flown 34 missions, most to the International Space Station, and is one of the most trusted shuttles in the NASA fleet. Discovery's 2006 Return to Flight mission brought Expedition crews to and from the ISS, but had problems with foam shedding that were similar to the Columbia disaster. The mission returned safely on July 17, 2006.
John Glenn was an American astronaut, engineer, and politician. He was born in 1921 in Ohio and studied engineering. In 1962, he became the first American to orbit Earth aboard Friendship 7, making him a national hero. Glenn had a long career as a test pilot and was one of the original NASA Mercury astronauts. He received numerous honors for his service and accomplishments in aviation and space exploration.
1) A senior NASA official said that future space agencies and commercial firms may offer one-way tickets to space, with travelers accepting they would not return, to explore distant worlds like Mars and beyond.
2) NASA's goal is to return to the Moon as a stepping stone to Mars and eventually explore asteroids and other destinations in the solar system.
3) However, a physicist said even a one-way trip to the nearest star Alpha Centauri was currently beyond our physical capabilities, and multi-generational space arks posed profound ethical questions.
John Glenn was born in 1921 in Ohio. He studied engineering in college and became an astronaut for NASA's Project Mercury. On February 20, 1962, Glenn became the first American to orbit Earth aboard Friendship 7. He inspired the nation and was hailed as a national hero. Glenn had a long career as a pilot, flying over 100 missions for the Marines in World War II and Korea. He later served as a US Senator from Ohio. Glenn continued to advocate for science and space exploration throughout his life.
NASA and AARP celebrate 50 years of space exploration achievements including inspiring future generations, creating new jobs and technologies, and increasing discovery and knowledge of Earth and space. Key events include President Kennedy's 1962 speech advocating for space exploration, the 1969 Apollo 11 mission that landed the first humans on the Moon, and ongoing work at the International Space Station to enable future exploration.
President John F. Kennedy encouraged the space program to send Americans to the moon to achieve preeminence in space for the United States and carry out scientific exploration of the moon. Several uncrewed and crewed Apollo missions tested equipment and modules, with Apollo 11 achieving the first lunar landing in 1969. Tragedy struck in 1967 when a fire during a launch pad test killed three astronauts. Later Apollo missions continued lunar exploration through 1972, including Apollo 13 which had to make an emergency return to Earth after an oxygen tank explosion.
NASA was founded in 1958 in response to the Soviet Union's launch of Sputnik. Project Mercury launched America's first astronauts into suborbital and low Earth orbital flights between 1961 and 1963. Project Gemini developed orbital flight techniques from 1965 to 1966 in preparation for the Apollo program to land astronauts on the Moon. Apollo 1 ended in tragedy with the deaths of its crew during a launch pad test in 1967. The first successful manned Apollo mission was Apollo 7 in 1968, followed by Apollo 8 which orbited the Moon in 1968. Apollo 11 succeeded in landing the first humans on the Moon in 1969. A total of six manned lunar landings were made between 1969 and 1972, culminating with Apollo 17. These missions achieved President Kennedy's

Java is known for its high cold start times and high memory footprint, comparing to other programming languages like Node.js and Python. In this talk I'll look at the general best practices and techniques we can use to decrease memory consumption, cold start times for Java Serverless development on AWS including GraalVM (Native Image) and AWS own offering SnapStart based on Firecracker microVM snapshot and restore and CRaC (Coordinated Restore at Checkpoint) runtime hooks. I'll also provide a lot of benchmarking on Lambda functions trying out various deployment package sizes, Lambda memory settings, Java compilation options and HTTP (a)synchronous clients and measure their impact on cold and warm start times.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Blue Origin's New Shepard Resumes Space Tourism with Historic Passenger | GQ Research
1. Blue Origin’s New Shepard Rocket Returns To
Space Tourism After Hiatus
(Source – NewsBytes)
Blue Origin’s tourism rocket, New Shepard, has successfully launched passengers to the edge
of space for the first time in nearly two years. This marks the end of a hiatus that began after
a failed uncrewed test flight. The New Shepard rocket and capsule lifted off at 9:36 a.m. CT
(10:36 a.m. ET) from Blue Origin’s facilities on a private ranch in West Texas.
The mission, designated NS-25, is Blue Origin’s seventh crewed flight and carried six
passengers: venture capitalist Mason Angel; Sylvain Chiron, founder of the French craft
brewery Brasserie Mont-Blanc; software engineer and entrepreneur Kenneth L. Hess; retired
accountant Carol Schaller; aviator Gopi Thotakura; and Ed Dwight, a retired US Air Force
captain selected by President John F. Kennedy in 1961 to be the nation’s first Black astronaut
candidate.
Ed Dwight’s Historic Journey
Ed Dwight’s inclusion in this mission is particularly significant. Although Dwight completed
training at the Aerospace Research Pilot School and received an Air Force recommendation,
he did not ultimately join the NASA Astronaut Corps. Instead, he pursued a career as an
entrepreneur and sculptor. His story is featured in a new National Geographic documentary
on Black astronauts, “The Space Race.”
2. In the documentary, Dwight reflects on his unexpected journey to the edge of space: “I had
no intention of being an astronaut. That was the last thing on my bucket list,” he said. “But
once I was given the challenge, then everything changed.”
At 90 years old, Dwight became the oldest person to reach the edge of space, a milestone
highlighted by a Blue Origin spokesperson. After the capsule touched down at 9:46 a.m. CT
(10:46 a.m. ET), Dwight shared his feelings on the experience during Blue
Origin’s livestream: “I thought I didn’t need it in my life. But I lied. I really, really did need
it. It’s a life-changing experience. Everybody needs to do this.”
The Mission’s Success and Technical Details
The rocket booster landed safely a few minutes before the capsule, ensuring a smooth end to
the mission. During their journey, the crew experienced speeds exceeding 2,000 miles per
hour, or more than three times the speed of sound. The rocket-propelled the capsule past the
Kármán line, an internationally recognized boundary of outer space situated 62 miles (100
kilometers) above Earth’s surface.
At the peak of the flight, passengers enjoyed a few minutes of weightlessness and
breathtaking views of Earth through the capsule’s windows. This successful mission followed
the triumph of an uncrewed science mission in December, marking the first flight of the New
Shepard program since the previous mishap.
Blue Origin’s return to space tourism underscores the resilience and enduring appeal of
commercial space travel. As the industry continues to grow, such missions offer a glimpse
into the future of accessible space exploration for civilians.
