Russian Military Launches Secret Surveillance Satellite Into Orbit | Space

A Russian Soyuz rocket launched a top-secret military satellite designed to scope out other satellites in space on Monday (Nov. 25), according to government reports.

The Soyuz-2.1v launch vehicle brought the satellite into orbit from the Plesetsk Cosmodrome, which is roughly 500 miles or 800 kilometers north of Moscow, for the Russian Defense Ministry, the ministry said in a statement . The launch took place at 12:52 p.m. EST (1752 GMT or 8:52 p.m. local time).

Ariane 5 Rocket Launches Satellites into Orbit for Egypt, Inmarsat | Space

An Arianespace rocket launched two communications satellites launched into orbit today (Nov. 26) in a bid to increase connectivity for mobile, civil and government customers.

"What a journey that we have done together," Arianespace CEO Stephane Israel said after the launch. 

Tiba-1, the first satellite to deploy, is a satellite for Egypt that will be used for civil and government communications. It is Egypt's first government-owned telecommunications satellite. Two companies were the prime contractors: Thales Alenia Space and Airbus Defence and Space. They managed construction on behalf of the government of Egypt, which will operate the spacecraft.

PSLV delivers India’s highest-resolution Earth observation satellite to orbit –

Thirteen U.S.-built nanosatellites hitched a ride to space Tuesday with a sharp-eyed Indian Earth-imaging observatory at the top of a Polar Satellite Launch Vehicle.

India’s Cartosat 3 mapping satellite, 12 commercial SuperDove CubeSats, and an experimental tech demo nanosatellite rode the PSLV into orbit following a fiery blastoff from the Satish Dhawan Space Center at 10:58 p.m. EST Tuesday (0358 GMT Wednesday).

The 144-foot-tall (44.4-meter) rocket, powered by four stages and six strap-on solid rocket boosters, arced toward the southeast from the launch base on India’s southeast coast. A few minutes later, the rocket turned south in a “dogleg” maneuver to steer around Sri Lanka, avoiding flying over the island nation.

In case you are keeping track:

Thousands of Super-Earths could orbit huge black holes, says study

Planets tend to form out of protoplanetary disks – rings of dust and gas that circle stars. In these disks, grains of dust slowly stick together, creating bigger and bigger clumps, growing their mass and gravity which in turn attracts more loose matter, making them even bigger. Eventually, what you end up with is a system of planets of various sizes, smaller moons that get stuck orbiting those planets, and leftover crumbs drifting around in the form of asteroids and comets.

French startup ThrustMe found fast route to orbit through China's Spacety - SpaceNews.com

French propulsion startup ThrustMe unexpectedly made it into orbit early this month with its innovative propulsion system placed aboard a Chinese cubesat.

Dianfeng, or Xiaoxiang-1 (08), a six-unit cubesat developed by privately owned Spacety, was a secondary payload on the launch of the Gaofen-7 civilian Earth observation satellite Nov. 2, along with a first satellite for Sudan.

As with many Chinese launches, secondary payloads were not announced until after launch success was declared, but further surprises were aboard.

Is it safe to build a space elevator with so much junk in orbit? - MIT Technology Review

Every week, the readers of our space newsletter, The Airlock , send in their questions for space reporter Neel V. Patel to answer. This week: space elevators. 

For the uninformed, a space elevator is basically just what the name suggests: an elevator that takes you into space (have you never read Charlie and the Great Glass Elevator ??) The idea is that an elevator could bypass all the fire and noise and other expensive theatrics necessary to take a payload beyond the planet's atmosphere and into space. With a space elevator, you basically ride up into orbit as if you were going up to the top floor of the Burj Khalifa.
