Да прям отпускает. Вуз давал бумагу в котором было написано "такой то имеет право свободного трудоустройства". Но. Если принимающая сторона принимала такого бывшего студента на работу по этой бумаге, то она должна была заплатить вузу немерянные деньги за него.

With 2 More Cubesats in Orbit, Earth-imaging Startup Planet Laps Ships Next Batch of 28 to Wallops

SAN FRANCISCO — Planet Labs, the San Francisco company planning to establish the world's largest Earth imaging constellation, announced Nov. 26 the successful launch of two satellites and shipment to Virginia of 28 additional spacecraft in preparation for their December launch.
On Nov. 21, Planet Labs sent triple cubesats Dove 3 and Dove 4 into polar orbit on a Dnepr rocket from Russia's Yasny launch site. "The launch was extremely successful," said William Marshall, Planet Labs co-founder and chief executive. "They went into precisely the orbit we wanted. We have also successfully made contact."

The latest additions to the Planet Labs fleet offer improvements in the capability provided by the firm's first satellites launched in April, Dove 1 and Dove 2, which also were triple cubesats measuring 10 centimeters by 10 centimeters by 30 centimeters.

Dove 3 and Dove 4 will demonstrate the firm's latest technology, including upgraded communications, attitude control and observation technology. "We like to iterate our satellite designs very rapidly," Marshall said. "It's the same compact form factor as Dove 1 and Dove 2, but we have stuck in more capability."

Dove 2 launched April 19 on a Soyuz-2.1a rocket from Baikonur Cosmodrome in Kazakhstan. It rode into orbit as a secondary payload on the Bion-M1 biological experiment satellite. On April 21, Bion-M1 deployed the Dove 2 cubesat.

Dove 1 traveled April 21 on the maiden flight of Orbital Sciences Corp.'s Antares rocket. Dove 1 re-entered Earth's atmosphere six days later. Dove 2 remains aloft.

Now, Planet Labs is preparing for the scheduled launch Dec. 15 of its operational Earth imaging constellation of 28 satellites, dubbed Flock 1, onboard Orbital's Antares rocket destined for the international space station. Planet Labs completed production of the cubesats and shipped them in November to NASA's Wallops Flight Facility in Virginia for integration on the first of eight space station cargo transportation flights performed by Orbital's Antares rocket under NASA's Commercial Resupply Services program. 

After their launch in 2014, Planet Labs' Flock 1 cubesats are expected to occupy a 400-kilometer, circular orbit at an inclination of 52 degrees relative to the equator. 

By establishing a 28-satellite constellation, Planet Labs is seeking to provide Earth imagery at a higher resolution and with higher frequency than currently exists in the market. "This fleet will be acting a little bit like a line scanner for the Earth," Marshall said. "Every place on the Earth will be covered."
The Flock 1 constellation is designed to collect frequent imagery of latitudes within 52 degrees of the equator. Because Dove 3 and Dove 4 are in sun synchronous orbit, they will provide imagery of areas not observed by Flock 1, Planet Labs spokeswoman Tracy Nguyen said by email. 

The Flock 1 constellation is designed to provide imagery with a resolution of three to five meters, Marshall said. Company executives are eager to see the imagery used to support a wide array of environmental, humanitarian and business missions. 

"There is a great deal of interest from customers but we are not going to talk about any details of that at this time," Marshall said, citing the proprietary nature of many of those conversations. 
Planet Labs built the miniature satellites in its 740-square meter offices here, which house the firm's 35 full-time employees. In recent months, those offices also were home to Forest Stearns, an artist in residence who created a unique design for the cubesats.

"There is a panel on the side of the spacecraft that gets exposed when the solar arrays are unfurled," Marshall said. Stearns "put beautiful murals of flocking and herding birds, animals and fish on the side of the satellites. We take a lot of pride in our satellites. They are beautiful and we are trying to make them even more beautiful."

ISS Commercial Resupply Services Mission (Orb-1)

Launch Date:    No Earlier Than December 17, 2013

Launch Site:    Mid-Atlantic Regional Spaceport, Wallops Island, VA

Launch Window:    10:04 - 10:09 pm EST (03:04 - 03:09 am GMT 12/18/13)

Cygnus Arrival at ISS :    No Earlier Than December 20, 2013

An Antares rocket carrying Orbital's Cygnus cargo logistics spacecraft is scheduled to lift-off from Pad-0A at the Mid-Atlantic Regional Spaceport at Wallops Island, Virginia no earlier than December 17, 2013. Antares will boost Cygnus to a target orbit of 210 km by 298 km, from which Cygnus will use its on-board thrusters to raise its orbit to rendezvous and berth with the International Space Station (ISS). Berthing with the ISS is scheduled to occur on December 20, 2013. For this mission Cygnus will be carrying approximately 1459 kg (3,217 lbs.) of cargo to the ISS for NASA.

The Orb-1 mission is the first of eight commercial cargo resupply missions to the ISS under the NASA Commercial Resupply Services (CRS) contract, under which Orbital is slated to deliver up to 20,000 kg of supplies to the station.

Antares Mission Description

The two-stage Antares space launch vehicle utilizes a liquid-fueled first stage powered by two Aerojet Rocketdyne AJ26 engines and a solid motor ATK CASTOR 30B upper stage to boost Cygnus into orbit. The powered launch sequence will last about ten minutes from liftoff through the separation of Cygnus from the launch vehicle.

Cygnus Mission Description

After separation from Antares, Cygnus will deploy its solar arrays and undergo initial check-out. The spacecraft will conduct a series of thruster burns to raise its orbit to bring it within 4 km of the ISS prior to receiving authorization to autonomously rendezvous with the station. When the vehicle approaches to within 12 meters, the astronauts will use the station's robotic arm to grapple Cygnus and berth it to the Harmony node of the station. Cygnus is planned to remain berthed at the ISS for 42 days during which time the station crew will load Cygnus with materials for disposal. At the end of the mission Cygnus will depart the station and reenter the Earth's atmosphere.

Viewing the Launch

The Orb-1 launch will be broadcast on NASA TV and webcast on www.nasa.gov on launch day. In addition, NASA TV will provide live coverage of the rendezvous and berthing of Cygnus with the ISS.

You can follow the launch on Twitter @orbitalsciences and on Facebook.

Friday, December 6

Our Antares and Cygnus teams are in the advanced stages of preparation for the company's first operational resupply mission to the International Space Station under the Commercial Resupply Services (CRS) contract. The launch to the Station originating from the Mid-Atlantic Regional Spaceport (MARS) at NASA's Wallops Flight Facility is currently scheduled for Tuesday, December 17, at approximately 10:04 p.m.

Over the next 11 days, major operational events are scheduled to take place, beginning this weekend with the movement of the Antares rocket to the transporter/erector/launcher (TEL) and the mating of the Cygnus spacecraft with the Antares rocket that will carry it to orbit. Following the mating process, a series of tests to ensure all systems are properly working together will ensue, as will late- and final-loading of cargo, the encapsulation of Cygnus by the rocket's payload fairing, and finally, the roll-out and initial on-pad operations that are currently scheduled for December 15.

Кто-нибудь знает, каким образом планируется распылять 28 шт. Flock-1. Креббс у себя пишет, что тоже, с МКС, с манипулятора японского модуля.    

28 Flock-1 satellites are to be launched as piggy-back payloads on a single launch on an Antares-120 booster, which lofts the Cygnus 2 transporter towards the ISS, where they will be deployed from the Kibo airlock by Nanoracks deployers.

14 зарядок пускача?

Вообще, конечно, идея веселая. Они же короткоживущие, все эти кубсаты-отстреленные-от-МКС. То есть для того, чтобы поддерживать численность группировки такой вот системы ДЗЗ - надо ее постоянно пополнять. Японский астронавт устанет педаль нажимать (или чем там система отстрела управляется).

Monday, December 9
 The Antares team continued making progress over the weekend toward the launch of Orbital's first CRS resupply mission next week, however ongoing pre-launch testing took a bit longer than expected which resulted in shifting the targeted launch date by one day to December 18. In the next several days, the Antares rocket will be installed on the transporter/erector/launcher vehicle and the Cygnus spacecraft will be mated with the upper stage of the rocket. The launch window on December 18 is from 9:42 to 9:47 p.m.(EST). Additional updates will be posted in the days ahead.

Живут-то коротко, а вот трупики на такой орбите сколько пролетают?

[anik]

Полагаю, что под короткоживущими Sharicoff имел в виду то, что живут-то они долго, но орбита у них короткая. Или я не прав?  

[Sharicoff]

Имелись в виду именно сроки баллистического существования. Посмотрите на те пять кубсатов, которые были отстрелены в октябре 2012 года - они уже все сгорели (март, два в мае, июль и август 2013). То есть даже если предположить, что PlanetLabs'у удалось сделать кубсаты с САС 1 год (это вполне реально, такие примеры уже есть) - то все равно, для поддержания численности группировки им придется регулярно вбрасывать новые пачки спутников. Потому что "прошлогодних" уже не будет: сгорят.
