Diving and Driving on Icy
Moons: One Strategy for Exploring Enceladus and Europa
(Source: Space News)
Over the past 60 years, NASA has explored the solar system from the sun
to the Kuiper belt. While many of these missions, especially those
beyond Saturn, have been one-shot flybys (such as the Voyagers and
recently New Horizons), others have charted many of the moons of
Jupiter and Saturn extensively by repeated orbital passes. The sole
landing on these icy worlds was the Huygens probe, which parachuted to
the surface of Saturn’s moon Titan in early 2005 as part of NASA’s
Cassini mission, and which operated for about 90 minutes after
touchdown.
The data gathered from a few of these moons has provided compelling
evidence of possible warm oceans beneath their frozen surfaces,
Saturn’s Enceladus and Jupiter’s Europa in particular. NASA would like
to explore these subsurface seas, as they appear to offer promise for
the potential of life. Between their internal geological activity,
spurred by the torturous gravitational complexities of Jupiter and
Saturn’s many moons that heats these cold worlds, and the watery plumes
spouting from both, they are very compelling to planetary scientists
(especially exobiologists). (12/25)
Proton Launches Weather
Satellite at Baikonur Spaceport (Source: Space News)
A Proton rocket launched a Russian weather satellite Tuesday. The
Proton lifted off from the Baikonur Cosmodrome in Kazakhstan at 7:03
a.m. Eastern and placed the Electro-L No. 3 satellite into its planned
transfer orbit six and a half hours later. The launch was the fifth
Proton mission of the year, four for the Russian government and one
commercial mission brokered by International Launch Services. There are
no commercial Proton launches scheduled for 2020, with Khrunichev
planning three Proton missions and two flights of Proton's eventual
successor, the Angara 5. (12/26)
Mitsubishi Develops Small
Satellite (Source: Space News)
A JAXA contract could help Mitsubishi get into the smallsat
constellation market. The Japanese space agency awarded a contract to
Mitsubishi Electric to build a 100-kilogram smallsat, called Innovative
Satellite Technology Demonstration-2, for launch in 2022. The company
said the satellite in intended to demonstrate its ability to serve as a
"standardized platform" for smallsats that could be produced in large
numbers. (12/26)
Russian Satellite Hit by
Micrometerorite or Space Debris (Source: TASS)
A Russian weather satellite reportedly was struck by a micrometeorite
or orbital debris last week. Roscosmos said Tuesday that the Meteor-M
No. 2-2 satellite malfunctioned after an "external influence" changed
the spacecraft's orbit and caused it to spin up. Controllers were able
to restore operations of the satellite. Roscosmos said "presumably a
micrometeorite" caused the problem, but didn't explain how it reached
that conclusion. The satellite was launched into polar orbit in July.

Russia Willing to
Participate in NASA Lunar Gateway (Source: Sputnik)
The head of Roscosmos says Russia is willing to participate in NASA's
lunar Gateway program. Dmitry Rogozin said Tuesday that Roscosmos is
ready to negotiate with NASA on Russian roles for the Gateway. Russian
officials had previously suggested they were not interested in
contributing to a project run by NASA. The other major partners in the
International Space Station — Canada, Europe and Japan — have all
announced their intent to take part in the Gateway. (12/26)
China's Commercial Space
Industry is Soaring (Source: Globa Times)
China's commercial space sector is growing rapidly and its development
is reaching a climax this year with domestic players making technology
breakthroughs, executives and industry analysts told the Global Times.
"For both players with state-owned enterprise backgrounds or
private-invested, this year means harvesting the gains" of past
efforts, said Huang Zhicheng, an expert in the space industry.
The overall atmosphere is very dynamic, Huang told the Global Times.
Earlier this month, two solid-fueled Kuaizhou-1A rockets were fired
into orbit from the same spaceport in northern China with a gap of less
than six hours. Kuaizhou-1A is a low-cost solid-fuel carrier rocket
with high reliability and a short preparation period. The rocket,
developed by a company under the China Aerospace Science and Industry
Corp (CASIC), is mainly used to launch low-orbit microsatellites.

Carrier Rocket Launched in China (Source: Xinhua)
A commercial suborbital carrier rocket developed by a private Chinese
company was launched from the Jiuquan Satellite Launch Center in
northwest China at 4:50 p.m. Wednesday (Beijing Time). The rocket,
Tansuo-1, was developed by Space Trek. It completed the whole maneuver
flight and fairing separation at high dynamic pressure during the
flight. The rocket can serve purposes of meteorological observation,
microgravity testing as well as satellite payload experiments. It was
the maiden flight of the first rocket developed by the company. (12/25)
China's Reusable Liquid
Rocket Engine Completes 500-Second Test (Source: Xinhua)
China's 15-tonne reusable liquid oxygen-methane engine completed a run
test with a duration of 500 seconds in Beijing on Wednesday. The
engine, named JD-1, was developed by the Beijing-based rocket company
i-Space, which is China's first private developer to send a rocket into
orbit. As the key to the reuse of carrier rockets, the engine was
designed to be used up to 30 times. It can save more than 70 percent in
manufacturing cost for the rockets, according to the developer.
The engine can meet multi-mission requirements such as deceleration,
landing, as well as long time in orbit and deep space exploration. It
has a strong adaptability to missions, the developer said. The engine
will be assembled on the reusable liquid oxygen-methane carrier rocket
Hyperbola-2, which was developed by i-Space. The rocket, with a takeoff
weight of 90 tonnes, is capable of sending 1.9 tonnes of payloads to
the low-Earth orbit. It is expected to be launched for the first time
in 2021. (12/25)

After 'The Expanse' Move
to Amazon Prime, Actors Hope to Film in Space (Source:
Space.com)
Actor Steven Strait has portrayed spacefaring captain James Holden on
the small screen since "The Expanse" first aired on the Syfy channel in
2015. Now that the series has a new home on Amazon Prime, Strait and
other cast members have quipped that maybe they can finally shoot on
location. In October, New York's Javits Center opened its doors for the
highly anticipated, four-day long marathon of nerdom known as New York
Comic Con. The convention grows each year; many projects, like "The
Expanse," choose to unveil their latest news at the event.
Naren Shankar, executive producer of the "The Expanse," joined Strait
and other cast members on a panel to answer fans' questions following a
special screening of the Season 4 premiere. The new season kicks off
the show's stay at Amazon Prime, the streaming service from billionaire
Jeff Bezos, who also founded the private spaceflight company Blue
Origin. The overlap is not lost on the "Expanse" cast. Paraphrasing a
fan's question, panel moderator Kyle Hill asked the cast, "How is it to
act like you're in space? It can't be an easy thing, not many people do
it, and there are lots of little tips and tricks you all have to make
space feel 'spacey.'" "We're hoping to shoot on location next year,"
Strait said. The crowd got hyped. (12/24)

Prosecutors sent 80 orders to the investigating authorities to initiate
criminal cases over violations discovered during the construction of
the Vostochny cosmodrome, Spokesman for the Russian Prosecutor
General's Office Alexander Kurennoy said Tuesday. According to the
