NASA gives up on salvaging InSight Mars lander’s ‘mole’

January 19, 2021 Stephen Clark

NASA managers tried for the last time earlier this month to coax the InSight lander’s long-stuck subsurface heat probe into the Martian soil, but after seeing no more progress, ground teams decided to end their efforts and focus on the mission’s other science objectives.

Hydraulic system issue triggered early engine shutdown during SLS test-firing

January 19, 2021 Stephen Clark

NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket’s core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are “feeling pretty good” about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.

Boeing making progress on Starliner software for test flight in March

Boeing said Monday it has re-qualified software for the company’s Starliner crew capsule after programming errors cut short the spacecraft’s first orbital test flight in 2019, and technicians at the Kennedy Space Center have connected the crew and service modules for the next unpiloted Starliner test flight to the International Space Station in March.

Virgin’s satellite launcher reaches orbit for first time

An air-launched rocket built by Richard Branson’s Virgin Orbit reached orbit Sunday for the first time, delivering 10 experimental CubeSats for NASA and positioning the company for the start of commercial operations.

NASA studying cause of early end to moon rocket test-firing

January 17, 2021 Stephen Clark

A critical test-firing of NASA’s Space Launch System moon rocket in Mississippi ended just 67 seconds after it began Saturday, well short of a planned eight-minute burn that was supposed to clear the way for the space agency to finally ship the rocket’s core stage to the Kennedy Space Center in Florida for launch preparations.

Video: SLS core stage test-firing ends early

January 16, 2021 Stephen Clark

The four RS-25 engines at the bottom of NASA’s first Space Launch System core stage shut down about a minute into a ground test-firing Saturday that was supposed to last more than eight minutes.

NASA takes a chance on Virgin Orbit with company’s second test launch

January 16, 2021 Stephen Clark

On its second launch attempt after a propulsion problem prevented its light-class air-dropped rocket from reaching space last year, Virgin Orbit will try to deliver 10 experimental CubeSats into orbit as soon as Sunday on a mission booked by NASA five years ago for $4.7 million.

Live coverage: SLS core stage engines shut down early during critical hotfire test

January 16, 2021 Stephen Clark

A critical test-firing of the Space Launch System’s core stage engines cut off about a minute into a planned eight-minute burn Saturday on a test stand at NASA’s Stennis Space Center in Mississippi. The rocket’s four engines ignited at 5:27 p.m. EST (2227 GMT) for a test that was to pave the way for the core stage’s shipment to the Kennedy Space Center for launch preparations.

NASA proceeds with SLS booster stacking in Florida before core stage arrives

January 15, 2021 Stephen Clark

NASA ground crews at the Kennedy Space Center are continuing to stack segments of the Space Launch System’s side-mounted solid rocket boosters on a mobile launch platform inside the iconic Vehicle Assembly Building.

NASA’s huge moon rocket faces critical test-firing before first launch

January 15, 2021 William Harwood

A critical test firing Saturday of the four main engines powering the first stage of NASA’s gargantuan Space Launch System moon rocket is the final major hurdle before the fully assembled booster’s costly, oft-delayed launch late this year on an unpiloted test flight.
