US, Jan 27, 2017: Fifty years ago today, January 27, 1967, tragedy struck NASA’s proposed first manned flight of the Apollo capsule when a fire engulfed the craft during a routine test on the launchpad.

All three American astronauts on board died in the fire: Lt. Col. Virgil “Gus” Grissom, Lt. Col. Edward White II and Roger B. Chaffee.

The tragedy stunned the nation, and it temporarily stalled NASA’s push to meet then-president John F. Kennedy’s deadline to reach the lunar surface by the end of the decade

A NASA probe and congressional hearings concluded previously unidentified fire hazards existed inside the capsule, and the subsequent decision to pressurize it entirely with oxygen created an extremely combustible environment. The hatch opened inward, which made it difficult for the crew to open it and escape.

After the deadly accident, hundreds of changes to the capsule were made, and NASA instituted myriad safety procedures. The redesigned capsules used a mixture of oxygen and nitrogen, reducing the fire risk. A new hatch was designed that could be opened in just five seconds.

Only 21 months later, NASA sent humans back into space aboard Apollo 7. And less than a year after that, Neil Armstrong and Buzz Aldrin landed Apollo 11 on the moon.

Rocket Lab is Set To Launch 10 NASA CubeSats

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space

In its first mission for NASA, the American aerospace manufacturer Rocket Lab is set to launch 10 small research satellites, or CubeSats, from New Zealand, the US space agency said.

Owing to bad weather, Rocket Lab was forced to postpone the earlier decided launch on December 12.

Rocket Lab is now targeting the ELaNa-19 launch on December 15 with a launch window opening at 11 p.m. EST from the company’s launch complex on the Mahia Peninsula in New Zealand, NASA said in a statement on Friday.

The CubeSats were built by three NASA centres, seven universities, and a middle school under the NASA’s Educational Launch of Nanosatellites, or (ELaNa-19) mission.

ElaNa-19 is NASA’s first to be completely dedicated to launching CubeSats under the agency’s Venture Class Launch Services program for small-satellite launches.

More than 250 students have been involved in the design, development and construction of the CubeSats scheduled to be flown as payloads on Rocket Lab’s Electron rocket.

“The major difference between today’s launch and previous #ELaNa missions is that for the first time, NASA will have a launch completely dedicated to CubeSats rather than having the small satellites ride along with a much larger spacecraft that is the primary mission,” NASA Launch Services Program officials wrote on Twitter on December 12.

The 10 CubeSats are named as CubeSail, CeREs, NMTSat, CHOMPTT, ALBus, STF-1, ISX, RSat, Shields-1 and DaVinci, NASA said.

These are built to standard dimensions of one unit (1U), and can be 1U, 2U, 3U or 6U in size. They generally weigh less than 1.33 kg per U — 6U may be up to 12 kg.

They will be placed in RailPODs aboard the Electron rocket that will ferry them to space.

After the main payload deploys, the CubeSats will separate from their RailPODs. After 45 minutes in orbit, the CubeSat transmitters will turn on and university ground stations will listen for their beacons, determine their small satellites’ functionality and announce operational status.

CubeSat mission durations and orbital life vary but are anticipated to last at least three years. Upon mission completion, the CubeSats fall to Earth, burning up in the atmosphere, NASA noted. (IANS)
