The Department of Defense (DoD) Space Test Program-2 (STP-2) mission, managed by the U.S. Air Force Space and Missile Systems Center (SMC), will deliver 23 satellites to space on the DoD's first ever SpaceX Falcon Heavy launch vehicle.

The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours.

In addition, the U.S. Air Force plans to reuse side boosters from the Arabsat-6A Falcon Heavy launch, recovered after a return to launch site landing, making it the first reused Falcon Heavy ever flown.

ЦитатаDSX

The Air Force Research Laboratory's Space Vehicle Directorate's Demonstration and Science Experiments (DSX) spacecraft will conduct basic research on the harsh radiation environment of medium-Earth orbit (MEO). DSX will perform three primary experiments:
    [/li]
  • The Wave Particle Interaction Experiment (WPIx) will resolve critical feasibility issues for very-low frequency (VLF) wave-particle interaction.
  • The Space Weather Experiments (SWx) will measure and map the distributions of energetic protons, electrons and low-energy plasma in the inner magnetosphere to improve environment models for spacecraft design and operations.
  • The Space Environment Effects (SFx) will determine the MEO environmental effects on common electrical components, circuits and materials. This includes NASA's Space Environment Testbeds (SET) experiments. SET will characterize how radiation driven by the Sun impacts hardware over time, paving the way for mitigating the effects of solar activity on spacecraft design and operations.

ЦитатаCape Canaveral preparing for key military launches
by Sandra Erwin -- April 24, 2019

The Air Force 45th Space Wing is gearing up for three high-profile space launches at Cape Canaveral over the coming months. If all goes as planned, ... the Space Test Program-2 missions will fly in June.

... the Air Force Space and Missile Systems Center is getting ready to launch STP-2. This will be Falcon Heavy's third launch and, of larger significance to the Air Force, it will be powered by reused side boosters from the rocket's recent Arabsat mission, paving the way for the Air Force's future certification of reused rockets.

"This is exciting for the Air Force as we look to increase reusability in the future," Brig. Gen. Doug Schiess, commander of the Air Force 45th Space Wing and director of the Eastern Range at Patrick Air Force Base, Florida, told SpaceNews. The range has two landing pads for returning boosters that has been used only by SpaceX but could be made available to others as well, he said. No date has been set yet for STP-2 but Schiess estimates it could happen in June.

STP-2
The Defense Department's Space Test Program-2 (STP-2) mission will deliver 23 satellites to space on DoD's first Falcon Heavy launch. SpaceX has characterized this as one of its most challenging launches -- a six-hour-plus mission with four separate upper-stage engine burns and three separate deployment orbits. The reuse of the side boosters from the Arabsat-6A Falcon Heavy launch in April makes this the first reused Falcon Heavy ever flown. SMC will use STP-2 as a pathfinder for the development of mission assurance policies and procedures on the reuse of launch vehicle boosters. This mission is four years late, as it was originally planned for mid-2015. Delays were caused by Falcon Heavy development setbacks and Falcon 9 failures in 2015 and 2016.

LightSail 2 Integrated with Prox-1 Carrier Spacecraft

LightSail 2 is officially on the road to launch.

The Planetary Society's solar sailing CubeSat has successfully shipped to the Air Force Research Laboratory (AFRL) in Albuquerque, New Mexico, where it was integrated with Prox-1, the Georgia Tech-designed spacecraft that will carry LightSail 2 to orbit aboard a SpaceX Falcon Heavy rocket. The joining of the two spacecraft marked a key mission milestone, as LightSail 2 passed fr om its Planetary Society-led team's hands for what is expected to be the last time.

"After years of work by our mission team preparing and testing LightSail 2, we are very excited to see it off on its journey," said LightSail Program Manager and Planetary Society Chief Scientist Bruce Betts. "We look forward to next communicating with LS2 in space!"

The integration procedure began on 6 May 2019, when engineers at Cal Poly San Luis Obispo in California removed LightSail 2 from storage and carefully packaged it for shipment:

LightSail 2 sits inside a protective case prior to a 6 May 2019 flight to Albuquerque, New Mexico for final integration with the Prox-1 spacecraft at the Air Force Research Laboratory (AFRL).

Integration with Prox-1 took place the following day, on 7 May 2019. Nugent said the process only took 2 hours and went very smoothly. This was LightSail 2's second integration with Prox-1; the spacecraft was first integrated in March 2018, but launch delays prompted the team to bring the CubeSat back to Cal Poly so its batteries could be periodically charged.

In April, Alex Diaz, an engineer at Ecliptic Enterprises Corporation, updated the spacecraft's software, topped off the batteries, and performed an "aliveness test"--a series of checks to make sure the spacecraft responded properly to basic commands.
Prox-1 and LightSail 2 will soon ship to Cape Canaveral, Florida, wh ere they will be attached to the SpaceX Falcon Heavy rocket flying the STP-2 mission for the U.S. Air Force. NASA, which also has payloads on the rocket, reports the launch is currently scheduled for no earlier than 22 June 2019.

For centuries, people have dreamed of using solar sails to travel the cosmos. In 2019, The Planetary Society's LightSail 2 will help make that dream a reality by attempting the first, controlled solar sail flight in Earth orbit. The spacecraft was made possible thanks to the generous support of space enthusiasts from around the world.

LightSail 2 set to launch next month aboard SpaceX Falcon Heavy rocket

The Planetary Society's LightSail 2 spacecraft is ready to embark on a challenging mission to demonstrate the power of sunlight for propulsion.

Weighing just 5 kilograms, the loaf-of-bread-sized spacecraft, known as a CubeSat, is scheduled to lift off on 22 June 2019 aboard a SpaceX Falcon Heavy rocket fr om Kennedy Space Center, Florida. Once in space, LightSail 2 will deploy a boxing ring-sized solar sail and attempt to raise its orbit using the gentle push from solar photons.

It's the culmination of a 10-year project with an origin story linked to the 3 scientist-engineers who founded The Planetary Society in 1980.

"Forty years ago, my professor Carl Sagan shared his dream of using solar sail spacecraft to explore the cosmos. The Planetary Society is realizing the dream," said Planetary Society CEO Bill Nye. "Thousands of people from all over the world came together and supported this mission. We couldn't have done it without them. Carl Sagan, and his colleagues Bruce Murray and Louis Friedman, created our organization to empower people everywhere to advance space science and exploration. We are go for launch!"

THE DREAM OF SOLAR SAILING - LIGHTSAIL 2
For centuries, people have dreamed of using solar sails to travel the cosmos. In 2019, The Planetary Society's LightSail 2 will help make that dream a reality by attempting the first, controlled solar sail flight in Earth orbit. The spacecraft was made possible thanks to the generous support of space enthusiasts from around the world.

If successful, LightSail 2 will become the first spacecraft to raise its orbit around the Earth using sunlight. While light has no mass, it has momentum that can be transferred to other objects. A solar sail harnesses this momentum for propulsion. LightSail 2 will demonstrate the application of solar sailing for CubeSats, small, standardized spacecraft that have made spaceflight more affordable for academics, government organizations, and private institutions.

LightSail 2 will ride to space aboard the Department of Defense's Space Test Program-2 (STP-2) mission scheduled for launch on 22 June 2019, which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demonstrate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 7 days after launch.

LIGHTSAIL 2 AND PROX-1
Prox-1 deploys the LightSail 2 spacecraft in Earth orbit.


After a few days of health and status checks, LightSail 2's 4 dual-sided solar panels will swing open. Roughly a day later, 4 metallic booms will unfurl 4 triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters, will turn towards the Sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount.

The Planetary Society launched a nearly identical spacecraft called LightSail 1 in 2015 that successfully tested the spacecraft's sail deployment system. LightSail 2 will fly to an orbit 720 kilometers high, wh ere the acceleration from sunlight overcomes atmospheric drag. The spacecraft may be visible in the night sky for a year to observers within 42 degrees of the equator, which includes the U.S. as far north as Chicago and New York.

The Society launched a larger sail named Cosmos 1 in 2005 that did not reach orbit after a failure of the spacecraft's Russian-built rocket. Planetary Society co-founder Louis Friedman led a 1970s NASA solar sail study that would have sent a spacecraft to rendezvous with Halley's Comet. Fellow Society co-founder Carl Sagan showed off a model of the spacecraft on The Tonight Show with Johnny Carson in 1976.

Results from the LightSail 2 mission are already helping to inform future solar sail projects by other organizations. NASA's NEA Scout spacecraft will launch to the Moon aboard the first Space Launch System flight and use a solar sail to visit a near-Earth asteroid. The Planetary Society shares LightSail project data with NASA through a Space Act Agreement.

The LightSail project started in 2009. The spacecraft was built by Stellar Exploration, Inc. The lead contractor for integration and testing is Ecliptic Enterprises Corporation, with testing, storage and ground support provided by Cal Poly San Luis Obispo. Planetary Society Chief Scientist Bruce Betts serves as the LightSail program manager. The project manager and mission manager is Purdue University's David Spencer.
