Starship Makes Long Awaited Hop at
Texas Spaceport (Source: Space News)
A SpaceX Starship prototype made a long-awaited brief test flight
Tuesday evening. The Starship SN5 vehicle lifted off from the company's
Boca Chica, Texas, test site shortly before 8 p.m. Eastern, touching
down on a neighboring pad about 45 seconds later after flying to an
estimated altitude of 150 meters. The "hop" test was the first free
flight of a Starship prototype. Last September, SpaceX CEO Elon Musk
said such a flight would take place in one to two months, but several
previous prototypes were destroyed in ground tests. (8/5)
DoD's SDA Wants Fast Action on
Military Constellations (Source: Space News)
The head of the Pentagon's Space Development Agency (SDA) says he wants
to move quickly in developing constellations of satellites. Derek
Tournear said Tuesday that the motto of the agency, "semper citius" or
"always faster," is intended to emphasize the idea that good enough
capabilities in the hands of troops sooner is preferable than
delivering the perfect solution too late. The first satellites that SDA
plans to start deploying in 2022 will be a mix of surveillance sensors
to help the military find targets on the ground and heat-tracking
sensors to locate missiles in flight that might be aimed at U.S. or
allied forces. (8/5)
NOAA to Use Commercial Satellite Data
for Operational Weather Forecasting (Source: Space News)
NOAA is seeking proposals for the purchase of commercial satellite
weather data for operational missions. NOAA is inviting companies to
submit proposals within the next 30 days to offer radio occultation
data under two-year indefinite delivery, indefinite quantity orders.
NOAA has previously purchased such data in a pilot program, but used it
only to evaluate its quality. The upcoming purchases will be for data
that will be used to support weather forecasting models. (8/5)
PredaSAR Plans 48 Satellite
Constellation (Source: Space News)
PredaSAR plans to launch at least one, and as many as 48, satellites
with SpaceX. The company, which is developing a constellation of
synthetic aperture radar satellites, said Tuesday it will launch its
first satellite on a Falcon 9 rideshare mission in the spring of 2021.
PredaSAR hopes to use SpaceX to launch the remainder of its
48-satellite system, but has not yet signed contracts for them. The
company declined to say when it expects to have all 48 satellites in
orbit, or to state the resolution of the constellation. (8/5)

NASA's Science Mission Directorate has a new office to coordinate
rideshare launches of its smallsats. The office works to identify NASA
science missions whose launches have excess capacity and arrange for
using that additional performance for launching smallsats for NASA or

two years ago to increase its use of small satellites for a variety of
science missions. (8/5)

seeking proposals for student experiments that could fly on the
Chang'e-7 mission, which will send an orbiter and lander to the moon,
landing in the south polar regions of the moon in 2024. Also in

Lunapolitics: 10 Points to Consider
(Source: Space News)
Renewed competition for the moon is the basis for the rise of
Lunapolitics: where political and economic interests intersect with the
topography and physical properties of the moon, from its subsurface
through to cislunar space. The competitors are primarily the United
States and China, but also Europe, Japan, India, and Russia, as well as
companies hoping to mine the moon’s resources. Lunapolitics is the
equivalent of geopolitics, and it is a growing and important reality
that will keep diplomats, executives, and strategists busy for decades
to come. Click here.

Rocket Lab announced Aug. 4 it has increased the payload capacity of
its Electron launch vehicle thanks to improvements in the batteries
used in the rocket. Rocket Lab previously promoted a payload capacity
of 150 kilograms to a 500-kilometer sun-synchronous orbit (SSO) and 225
kilograms to lower orbits. The company now says the vehicle can place
200 kilograms into SSO and 300 kilograms in lower orbits. (8/4)
Astronauts Praise 'Flawless' SpaceX
Capsule Landing (Source: Space Daily)
Two NASA astronauts who returned from space to a splashdown in the Gulf
of Mexico on Sunday praised the SpaceX Dragon capsule's performance in
their first public comments since the mission. "We're so proud of the
SpaceX and NASA teams to get Dragon through its first crewed flight
flawlessly," Doug Hurley said. "I'm almost kind of speechless, as far
as how well the vehicle did and how, how well the mission went and all
the things we did on board [the International Space Station]."
Hurley and Bob Benken spent 64 days in space after lifting off May 30
from Kennedy Space Center in Florida. Their assessment of the trip is
important because the flight was the last test of the Crew Dragon
capsule before NASA considers certifying it for regular flights. The
space agency still must pore over data from the flight, which could
take weeks. If all goes well, the first regular SpaceX mission will be
scheduled for as early as late September. (8/5)
SES Picks ULA for Launching Two

agreements follow contracts with manufacturers Boeing and Northrop
Grumman signed in June to build the satellites. SES emphasized its
decisions to purchase from U.S. companies amid pressure to rely on
American suppliers. ULA will launch two satellites from Boeing on an

Solar weather likely caused an NBN satellite to stop service for about

On Wednesday, after learning of SpaceX's Starship hop, President Trump
tweeted: "NASA was Closed & Dead until I got it going again. Now it

Force to go along with it. We have accomplished more than any
Administration in first 3 1/2 years. Sorry, but it all doesn’t happen

Space News' Jeff Foust tweeted a fact-check: "NASA was neither closed
nor dead at the start of the current administration. Many recent NASA
successes have their origins in prior administrations. The Starship
test the president is retweeting has nothing to do with NASA; it’s a
private effort by SpaceX." (8/5)
