SpaceX test-fires reused rocket in preparation for space station cargo mission

June 23, 2018

A rocket booster SpaceX used to launch a planet-hunting NASA observatory two months ago fired again Saturday at Cape Canaveral, clearing a major pre-flight checkout before blastoff June 29 with a space station supply ship.

JWST beset by another problem as Northrop Grumman revamps training

May 8, 2018

Engineers working on the James Webb Space Telescope, which had its launch delayed to 2020 earlier this year, recently discovered another problem during testing at the observatory’s prime contractor Northrop Grumman in Southern California.

Webb telescope’s launch delayed until 2020

March 27, 2018

Blaming a slew of technical snags and “avoidable errors,” NASA officials said Tuesday that the launch of the James Webb Space Telescope, already years behind schedule, will be delayed to 2020, potentially pushing the mission’s development cost above an $8 billion cap mandated by Congress.

Spacewalking astronauts complete robot arm work

February 16, 2018

Astronaut Mark Vande Hei and Japanese crewmate Norishige Kanai floated outside the International Space Station Friday, repositioned two robot arm grapple mechanisms following repair work last month and carried out a variety of “get-ahead” tasks before calling it a day.

Software patch fixes station robot arm; Monday spacewalk repair called off

January 28, 2018

A corrective software patch has fixed a problem with a newly installed grapple fixture on one end of the International Space Station robot arm, NASA officials said Sunday. With the mechanism now fully operational, a re-planned spacewalk Monday to re-install a degraded unit has been called off.

Newly installed space station robot arm grapple fixture not operating properly

January 26, 2018

The grapple mechanism installed on one end of the space station’s robot arm during a spacewalk Tuesday is experiencing problems. It will be removed during a re-planned spacewalk Monday and the original fitting will be re-installed, NASA said Friday.

Spacewalkers complete repairs to station robotic arm

January 23, 2018

Two astronauts floated outside the International Space Station early Tuesday and replaced one of the grapple fixtures on the end of the lab’s robot arm, the first of two excursions over the next week to complete a complex overhaul that began with a pair of spacewalks last October.

James Webb Space Telescope completes critical end-to-end test

January 15, 2018

NASA’s $8.8 billion James Webb Space Telescope has completed critical end-to-end testing in a giant vacuum chamber at the Johnson Space Center, proving the telescope will work properly in the deep cold of space, bring starlight to a sharp focus and precisely track its astronomical targets when launched in 2019.

Spacewalk concludes with successful robot arm repair

October 5, 2017

Two astronauts ventured outside the International Space Station early Thursday and performed what amounted to hand transplant surgery on the lab’s Canadian-built robot arm, removing a crippled grapple fixture on one end of the space crane and replacing it with an on-board spare.

Station astronauts prep for spacewalk to repair robotic arm

October 5, 2017

Astronauts Randy Bresnik and Mark Vande Hei headed outside the International Space Station Thursday on a spacewalk to replace one end of the lab’s Canadian-built robotic arm, a changeout that engineers say will restore the device to full capability.
