Northrop Grumman Test
Fires Astronaut Protection System (Source: SpaceFlight

Sending crews to destinations such as the Moon and Mars is not easy. As
many within the space industry will tell you, one of the most harrowing
times during these missions is the first few minutes of the flight. A
test carried out today worked to make this tense period a little less
stressful for NASA’s mission managers.
On Dec. 13, 2018 at 11 a.m. MST, Northrop Grumman Corporation
test fired the abort motor for NASA’s Orion spacecraft Launch Abort
System (LAS). The test was carried out at the company’s remote
Promontory site in the deserts of Utah. Northrop Grumman (at the time
Orbital ATK) carried out the Qualification Motor 1 (QM-2) test back on
June 16, 2017, making this test QM-2.
The unique profile of the test saw the four motors activate and shoot
fiery plumes into the air. If they are ever required, the motors would
fire pointed toward Earth, today they were activated in the vertical
position, with the motors pointed skyward. Thursday’s activities were
carried out to see how the motor will perform under “cold” conditions
(under 27 F). (12/14)
If You Think Black Holes
are Strange, White Holes Will Blow Your Mind (Source: New
Scientist)
White holes are essentially black holes in reverse. World-leading
relativity theorist Bob Wald wrote that “there is no reason to believe
that any region of the universe corresponds to” a white hole – and this
is still the dominant opinion today. But several research groups around
the world have recently begun to investigate the possibility that
quantum mechanics could open a channel for these white holes to form.
The sky might be teeming with white holes.
The reason to suspect white holes exist is that they could solve an
open mystery: what goes on at the centre of a black hole. We see great
amounts of matter spiralling around black holes and then falling in.
All this falling matter crosses the surface of the hole, the “horizon”
or point of no return, plummets towards the centre, and then? Nobody
knows. (12/13)
ESA Director-General:
Agency Needs a Financial-Aid Strategy for Ariane 6 Rocket Builders
(Source: Space Intel Report)
The European Space Agency is actively looking for ways to direct
additional financial support to the Ariane 6 heavy-lift rocket’s
industrial manufacturers as part of a deal tied to belt-tightening
measures by those companies, ESA Director-General Jan Woerner said.
Woerner said no decision had been made on the form and amount of the
aid. (12/14)
Branson Ready to Fly
(Source: Space News)
Virgin Galactic founder Richard Branson says he expects to fly in space
next year on the first commercial SpaceShipTwo flight. Branson,
speaking after the test flight Thursday, said he thought as few as
three more test flights would be needed before operations shift to New
Mexico's Spaceport America, where commercial flights will take place.
"Sometime next year, once the testing is finished, then I'll do my
flight," he said. He added that Virgin would soon start selling tickets
again after a four-year hiatus, with slightly higher prices. Branson
said he estimated Virgin has spent as much as $1.5 billion in its space
efforts, which include small launch company Virgin Orbit and spacecraft
manufacturer The Spaceship Company. (12/14)
OneWeb Cuts Constellation
From 900 to 600 Satellites (Source: Space News)
OneWeb is cutting the size of its satellite constellation by a third,
crediting improved performance. Greg Wyler, founder of OneWeb, said the
company now plans to deploy 600 satellites for its initial low Earth
orbit broadband constellation versus 900. Wyler cited
better-than-expected performance of individual satellites as a reason
for reducing the number of satellites. Costs had also been an issue
amid reports the per-satellite cost was well above the original target
of $500,000. Wyler confirmed the satellites now cost more than $500,000
each, but only by a small amount. (12/14)
Space Force Legislation
Being Vetted by Space Council (Source: Space News)
The Pentagon is on "final approach" for its Space Force proposal.
Deputy Defense Secretary Patrick Shanahan said Thursday their
legislative proposal for establishing the Space Force is nearing
completion, but will be vetted by the National Space Council and Vice
President Mike Pence before being submitted to Congress. Shanahan said
that the Defense Department had made a decision on how to establish the
Space Force, but did not disclose it. He added that he would be happy
to work with Rep. Adam Smith (D-WA), the incoming chairman of the House
Armed Services Committee, on revising that proposal after Smith said
earlier this week he was opposed to creating a standalone Space Force
because of its costs. (12/14)
DARPA Tasked With
Reforming Space Procurement (Source: Space News)
Reforming space procurement is so difficult it's now a task for DARPA
to tackle. Mike Griffin, the undersecretary of defense for research and
engineering, sent a memo to DARPA earlier this month instructing them
to put together a team to develop proposals for the Space Development
Agency, the organization the Pentagon plans to develop to take over
procurement of space capabilities. Griffin asked DARPA to complete the
report within 45 to 60 days. (12/14)

Vice President Pence plans to attend next week's launch of the first
GPS 3 satellite. Pence said Wednesday he'll go to Cape Canaveral to see
next Tuesday's launch of the SpaceX Falcon 9 carrying the Lockheed
Martin-built satellite. He called the launch of the first of a new
generation of GPS satellites an "important step forward as we seek to
secure American leadership in space." Launch preparations are on
schedule, with the satellite encapsulated within its payload fairing
earlier this week. (12/14)

California Rescheduled for Tuesday (Source: Lompoc Record)
The launch of a classified military satellite has been rescheduled for
next Tuesday. United Launch Alliance said Thursday the Delta 4 Heavy
launch of a classified National Reconnaissance Office payload, a
mission designated NROL-71, is now scheduled for 8:57 p.m. Eastern Dec.
18 from Vandenberg Air Force Base in California. A problem detected in
the final seconds of the countdown last Saturday scrubbed the previous
launch attempt. (12/14)
NOAA Nominee Unlikely to
See Senate Vote Before New Congress (Source: New York

The White House's nominee to lead NOAA is unlikely to get a Senate vote
this year. Barry Myers was nominated in October 2017 to be NOAA
administrator but has faced opposition from Senate Democrats. Sen. Bill
Nelson (D-FL), ranking member of the Senate Commerce Committee, said it
will be "very difficult" to get a vote to confirm him before the end of
the current Congress. If the Senate does not hold a vote, the White
House would have to resubmit his nomination next year or nominate
someone else. (12/14)
NASA Seeks US Partners to
Develop Reusable Systems to Land Astronauts on Moon
(Source: Space Daily)
As the next major step to return astronauts to the Moon under Space
Policy Directive-1, NASA announced plans on Dec. 13 to work with
American companies to design and develop new reusable systems for
astronauts to land on the lunar surface. The agency is planning to test
new human-class landers on the Moon beginning in 2024, with the goal of
sending crew to the surface in 2028.
Through upcoming multi-phased lunar exploration partnerships, NASA will
ask American companies to study the best approach to landing astronauts
on the Moon and start the development as quickly as possible with
current and future anticipated technologies. The agency's leading
approach to sending humans to the Moon is using a system of three
separate elements that will provide transfer, landing, and safe return.
A key aspect of this proposed approach is to use the Gateway for
roundtrip journeys to and from the surface of the Moon. (12/14)
Ceres’ Surface Found to
Contain Building Blocks for Life (Source: SpaceFlight
Insider)
The surface of the dwarf planet Ceres holds high levels of organic
material, according to a new study of images returned by NASA’s Dawn
spacecraft. This provides a tantalizing glimpse into the possibility of
life throughout our solar system. Scientists at the Southwest Research
Institute (SwRI) published a paper in the journal Nature Astronomy
noting the 4.6-billion-year-old dwarf planet, already known to harbor
water and volatile compounds, has a chemistry that strongly suggests it
formed in a colder environment than its current location in the
asteroid belt between Mars and Jupiter.
The presence of ammoniated clays on Ceres’s surface has led some
scientists to propose the small world may have formed in the Kuiper
Belt beyond the orbits of Neptune and Pluto, where ammonia would have
been scattered rather than vaporized by the Sun. An impact by another
Kuiper Belt Object (KBO) and/or the gravitational influence of the gas
giants could have knocked Ceres into the inner solar system about 500
million years after it formed, some researchers proposed in late 2015.
