Virgin Orbit Plans
Quick-Response Missions (Source: Space News)
As Virgin Orbit prepares for its first LauncherOne mission, the company
has a long-term vision of responsive launch. At a conference this week,
a company official outlined a "responsive launch enterprise" that makes
use of the company’s air-launch system to quickly deploy small
satellites. Such a system could launch an entire constellation within
several hours, using multiple aircraft flying from multiple spaceports.
The company emphasized this is a long-term vision, and didn't say how
long it would take to implement it and for how much money. (8/8)
What Happened to the
Promise of Hosted Payloads? (Source: Space News)
Hosted payloads, once considered a key way for the Air Force to fly
experimental payloads, have largely gone away. The Hosted Payload
Solutions (HoPS) contract vehicle, announced in 2014, has expired with
no plans by the Air Force to renew it. Several factors played a role in
the demise of hosted payloads, from the departure of champions of the
program within the Defense Department to technical, contracting and
cybersecurity challenges related to installing payloads on commercial
satellites. (8/8)
Russia Unveils Ambitious
Project for Laser Recharging of Satellites in Orbit
(Source: Sputnik)
Russian Military Space Academy experts claim the introduction of
refuelling satellites holds out the prospect of significantly extending
a spacecraft's life, as well as impressive cost-savings. Russia is
developing a "space gas station" - a group of robots that will use
lasers to recharge satellites in near-Earth orbit, Izvestia learned
from experts at the Alexander Mozhaysky Military Space Academy in St.
Petersburg. The prototype for the planned spacecraft is a spherical
object, with solar panels and photovoltaic modules. (8/8)
InVADER Project to Test
Technology for Exploring Ocean Worlds (Source: Space Daily)
Pablo Sobron, a SETI Institute physicist, and Laurie Barge, a NASA JPL
research scientist, are the recipients of a NASA Planetary Science and
Technology from Analog Research (PSTAR) grant to study underwater
hydrothermal systems at Axial Seamount, the largest and most active
volcano on the western boundary of the Juan de Fuca tectonic plate.
Their project, known as InVADER (In-situ Vent Analysis Divebot for
Exobiology Research), will transform the technological and operational
arsenal available for future ocean world exploration. The InVADER team,
which consists of scientists and engineers from other institutions in
the United States and Great Britain, will broaden the scientific
knowledge and techniques available to ocean sciences today. (8/9)
Something Big Just
Slammed Into Jupiter (Source: Gizmodo)
An amateur astronomer in Texas captured a rare sight earlier this week
when an apparent meteor slammed into Jupiter’s thick upper atmosphere.
On Wednesday, amateur astronomer Ethan Chappel was on the lookout for
Perseid meteors, reports ScienceAlert. But his telescope was trained on
Jupiter with the camera running. Later, after feeding the data into a
software program designed to detect impact flashes, Chappel was alerted
to the event.
Looking at the footage, Chappel saw a brief but discernible flash along
the western portion of Jupiter’s Southern Equatorial Belt, or SEB. The
flash appeared at at 4:07 a.m. UTC (12:07 a.m. ET) and lasted no longer
than a second and a half. Looking at the flash, the size of the
explosion seems small, but it’s important to remember that Jupiter is
the largest planet in the solar system. The meteor had to have been
quite big to produce a flash of such prominence. (8/9)
NASA Selects 15 Space
Biology Proposals Support Moon, Mars Exploration (Source:
NASA)
NASA has awarded 15 grants for new space biology research designed to
help the agency achieve its goals under the Artemis lunar exploration
program. Teams of investigators will use state-of-the-art genetic and
other biological techniques to explore how life adapts and changes
during spaceflight, and the results could help support human
exploration of the Moon, and ultimately, Mars.
Selected microbiology investigations will study whether changes in
bacteria, fungi, and viruses are likely to affect how they interact
with crew and material surroundings aboard the International Space
Station, with an emphasis on likelihood to cause infections and
microbial evolution. Editor's Note:
Three of the funded projects are in Florida. One at UF, one at FSU, and
one at KSC. Click here.

Shakeup at Vector Hints
at Financial Trouble (Source: Ars Technica)
Vector, a micro-launch company founded in 2016 to build small rockets
for payloads of up to 60kg, may be in financial trouble, multiple
industry sources told Ars on Friday. A spokeswoman for Vector did not
comment on that. However, she did confirm the company has parted ways
with its chief executive: "Jim Cantrell is no longer with Vector
effective today. John Garvey has assumed the role of CEO."
The company has been working on developing its Vector-R vehicle and
trying to prepare it for a suborbital flight this summer. In an
interview in April, Cantrell told Ars that he hoped to fly an upgraded
version, Vector-R B1003, on an orbital flight from the Pacific
Spaceport Complex in Alaska before the end of this year. The financial
difficulties have reportedly arisen just after Vector received some
good news in the form of a launch contract from the US Air Force.
The current setback comes as other companies are also racing to develop
smallsat launchers—although few were quite as small as the Vector-R,
which was powered by three LP-1 engines that produced a thrust of about
20,000 pounds and appeared to have a viable niche. It is widely
expected that the dozens of competitors seeking to develop smaller
rockets will see a funding crunch as some make it to the launch pad,
and others do not. Of these new space companies, only one, Rocket Lab,
has successfully begun commercial operations. (8/9)
Viasat Starts ViaSat-4
Development, Mulls Hybrid GEO-LEO-Terrestrial Connections
(Source: Space News)
Fleet operator Viasat, already in the middle of building a trio of
high-capacity broadband satellites, has started work on a
next-generation constellation, CEO Mark Dankberg said. A ViaSat-4
series is in early development, extensively leveraging research and
development on the 1-terabit-per-second or more ViaSat-3 satellites,
Dankberg said during an earnings call.
Viasat plans to launch its first ViaSat-3 satellite over the Americas
in early 2021, Dankberg said, with the second launching about six
months later to cover Europe, the Middle East and Africa. The third
should launch over the Asia-Pacific before the end of 2022, he said.

Hawaii Telescope Protest
Continues (Source: Nature)
There's no sign of progress in ending a protest that has closed off
access to observatories on Mauna Kea in Hawaii. Hundreds of protesters
continue to block the road leading to the mountain's summit to prevent
construction of the Thirty Meter Telescope (TMT) from starting. They
fear the observatory will disturb what native Hawaiians consider a
sacred location. A wide majority of Hawaiians, including native
Hawaiians, do support building TMT. The protests have closed the other
observatories on the mountain since mid-July. (8/8)
