NASA has replaced an astronaut set to launch to the International Space Station (ISS) in June with a backup.

Jeanette Epps, who was set to become the first African American crew member on the space station, has been reassigned to the Astronaut Office at NASA’s Johnson Space Center, the space agency announced. She will be considered for future flights.

“Serena Auñón-Chancellor, who previously was assigned to Expedition 58/59, has been reassigned to the Expedition 56/57 crew, launching in June,” NASA said in a press release. ” Anne McClain, a member of the 2013 astronaut class, will fly on the Expedition 58/59 crew, launching in November.”

NASA did not give provide a reason for the reassignment of Epps, who was selected as an astronaut in 2009.

First Commercial Flights to ISS Slide Toward 2020

Early in the classic police comedy, The Naked Gun, Lt. Frank Drebin (Leslie Nielsen) is at the hospital with partner Ed Hocken (George Kennedy) visiting the critically wounded Officer Nordberg (O.J. Simpson), who had been shot and left for dead by a group of heroin smuggling thugs.

“Doctors say that Nordberg has a 50/50 chance of living, though there’s only a 10 percent chance of that,” Ed tells Frank.

A similar scene played out Wednesday morning during the House Space Subcommittee’s hearing on the progress of NASA’s Commercial Crew Program. Only it wasn’t nearly as funny.

HOUSTON (NASA PR) — SpaceX’s Dragon cargo spacecraft splashed down in the Pacific Ocean on Saturday, Jan. 13, west of Baja California, with approximately 4,100 pounds of NASA cargo, science and technology demonstration samples from the International Space Station.

The Dragon spacecraft will be taken by ship to Long Beach, California, where some cargo will be removed immediately for return to NASA. Dragon then will be prepared for a return trip to SpaceX’s test facility in McGregor, Texas, for final processing.

NASA Audit Says CASIS Under Performing on Key ISS Research Tasks

by Douglas Messier
Managing Editor

The organization NASA hired to manage research aboard the International Space Station (ISS) has seriously under performed on the majority of its tasks, a new  audit from space agency’s Inspector General finds.

“Of the nine performance categories we assessed, CASIS met expectations in only two: research pathways and science, technology, engineering, and mathematics (STEM) education,” the report states. “For example, the STEM education performance category required CASIS to increase interest in using the National Lab as a platform for STEM education. CASIS met expectations for this performance category by funding 14 STEM education programs in FY 2016 with more than 325,000 participants.”

Commercial Crew Schedule Margins at Risk as Much Work Remains


by Douglas Messier
Managing Editor

NASA’s uninterrupted access to the International Space Station (ISS) could be at risk due to continued schedule slips by commercial crew providers Boeing and SpaceX, the NASA Aerospace Safety Advisory Panel (ASAP) said last week.

“Based on the quantity, significance, and associated uncertainty of work remaining for both commercial providers, the Panel believes there is a very real possibility of future schedule slips that could easily consume all remaining margin,” ASAP said in its annual report. [Full Report]

HOUSTON, January 10, 2018 (NanoRacks PR) — This morning, the NanoRacks External Platform (NREP) was reinstalled on the outside of the International Space Station, initiating the commercial platform’s third customer mission. The External Platform, self-funded by NanoRacks, is the leading commercial gateway to the extreme environment of space. Customers can experience the microgravity, atomic oxygen, radiation and other harsh elements native to the space environment. Additionally, customers can observe Earth, test sensors, materials, and electronics, all while having the opportunity to return the payload back to Earth.

NASA Commercial Crew Flights Slip Slide Toward 2019

Crucial flight tests for NASA’s two commercial crew vehicles are slipping ever closer to 2019. The space agency released the following updated schedules for Boeing’s CST-100 and SpaceX’s Dragon 2 vehicles today:

Targeted Test Flight Dates

Boeing Orbital Flight Test (uncrewed): August 2018
Boeing Crew Flight Test (crewed): November 2018
SpaceX Demonstration Mission 1 (uncrewed): August 2018
SpaceX Demonstration Mission 2 (crewed): December 2018

Boeing’s schedule has not changed from the previous update. SpaceX’s demonstration flights have slipped from April and August to August and December, respectively. No reasons have been given for the slips.

A reliable source tells Parabolic Arc that SpaceX experienced a delay several months ago due to issues with Dragon 2’s environmental control and life support system (ECLSS). The problem was estimated to delay the first demonstration flight about six months. At about that same time, the schedule for that first uncrewed flight slipped from February to April.

A SpaceX spokeswoman would not comment for the record on this report.

PARIS (ESA PR) — Astronauts on the International Space Station have begun running an experiment that could shine new light on how metal alloys are formed.

How humanity has mastered metallurgy is synonymous with progress, with historians labelling periods such as the Bronze Age and the Iron Age.

Most metals used today are mixtures – alloys – of different metals, combining properties to make lighter and stronger materials.

As space agencies from around the world are preparing to send people farther into the solar system, keeping astronauts safe and healthy during long missions will be critical. Canadian science conducted aboard the International Space Station (ISS) will help us better understand and offset the harmful effects of space on the human body (e.g. radiation exposure, which is a risk factor for cataracts and cancer; bone loss; muscle shrinkage; arterial stiffness; and weaker immune system).
