About our Mission and Spacecraft

The STM Sat-1 mission is to perform Earth observation and engage grade school students around the world as remote Mission Operation Centers. Our mission spacecraft satellite is very small. Spacecraft of this size are known as nano-satellites. This CubeSat model kit is very popular among amateur satellite builders.

Virginia School Launches Satellite (by Mark Albert)

March 5, 2016 – Astronauts on the International Space Station have conducted hundreds of experiments and launched many satellites, but now they are set to deploy a satellite that elementary age students at a school in Virginia built. Their satellite hitched a ride on a NASA rocket late last year, and it will be released into space in the next few days. Mark Albert reports.

Satellite Built by Elementary Students to be Launched in Space

February 2016 – Orbital ATK’s Cygnus spacecraft, the “Deke Slayton II”, has completed unberthing and separation operations from the International Space Station following a highly successful mission. The ISS crew released Cygnus at07:26 Friday morning (February 19th) after 72 days of docked operations.  It performed a destructive re-entry the next day.

This was our ride to the ISS, it served us well !

December 2015 –Cygnus cargo vessel carrying STMSat-1 has made it to the space station!  At 6:19am this morning, the Space Station robotic arm grasped the ORB-4 cargo element and mated it to the ISS.  A picture of the cargo element taken from the ISS is attached.

The ISS will be home to Cygnus (and STMSat-1) until on or about February 15th. On or about that day, the stmsat-1 will be launched with other CubeSats via a pea pod ejector and launched into low earth orbit. At that point, the timer starts for the programmed deployment of the antennas, the solar array, and the earth observation camera. Godspeed STMSat-1.  Please open the link below for additional information on the events of the day.

December 6, 2015 –at 21:44 UTC an Atlas V rocket blasted off from Kennedy Space Station.  The Cygnus spacecraft carrying STMSat-1 is on its way to the International Space Station!  Delivery is scheduled for Wednesday, December 9, 2015.

December 3, 2015 – STM CubeSat Will Launch From International Space Station From The Kennedy Space Center –  NASA video –

October 2015 – For more than three years now, STM students, faculty, staff and parents have been anxiously focused on the school’s participation in an effort to become the first elementary school “in the world” to develop, build and test a cube satellite suitable for launching to the International Space Station (ISS) as part of a NASA sponsored science and engineering program designed to involve educational institutions and their students in actual, real world space exploration and missions.

In February 6, 2014 St. Thomas More Cathedral School (STM) was among 16 institutions and laboratories to have their cube satellite concepts approved for potential deployment into outer space. Among the other notable institutions to join STM on that highly selective list were the likes of MIT, UCLA, the University of Michigan and Marquette University.

Following its selection, STM and its entire student body went into high gear in constructing its cube satellite, getting it tested and preparing it for delivery and further testing by NASA. Approval for launching was obtained in 2014, and an initial launch date was scheduled for later that year. Problems with rocket launches in September 2014 and early 2015 resulted in several postponements of STM’s tentative launch dates.

But it now appears to be time to actually “fasten your seatbelts everyone!!!”

STM’s cube satellite is now scheduled for launching on December 3, 2015, along with other supplies and experiments intended for delivery to the ISS, on top of an Atlas rocket set to take off out of the Kennedy Space Center at Cape Canaveral, Florida.

All systems appear to be “GO”, and if no further delays occur, STM is set to finally become the “first elementary school in the world”, to place a satellite into low earth orbit in outer space (albeit with NASA’s help, of course). Our cube satellite’s intended purpose is to photograph low altitude asteroids hurtling into earth’s atmosphere before burning up in our atmosphere.

So prepare to put on your best STM pride on big display and keep your antennae up for further developments as December approaches.

In the world of education, this could just be as big as SPUTNIK!!!!
“Godspeed STMSat-1”

June 2015 – The antenna was installed on top of the Mission Operations Center.

We have been assigned to a new launch. STMSat-1 will be launched to the International Space Station on November, 19th from the Kennedy Space Center.

The first task for the students when they return to school will be testing the Mission Operation Center communication system. They will be tracking and receiving data from Low Earth Orbit spacecraft.

Since the launch is now in Florida, the students will be able to view the launch in person.

Please continue to visit our website over the summer for the latest mission up-dates.

Godspeed STMSat-1 !

May 2015 – With the help of NanoRacks, the STMSat-1 spacecraft passed the fit-check with the flight deployment system and the vibration test.

April 2015 – Check out the latest images of the STMSat-1 Satellite (Flight Hardware)

February 2015 – St. Thomas More Cathedral School Establishes Canadian RMOC

October 2014 – The spacecraft is undergoing final flight integration. The solar arrays and deployable antenna will be installed next month. The spacecraft will go through a vibration test in January 2015. The flight hardware will be provided to the launch vehicle team in mid February 2015.

October 2014 – The students continue to participate in space related activities. This month they learned about Computer Aided Design (CAD), rapid prototyping (3D printing) and engineering model testing. The students will visit the Orbital Sciences Cygnus spacecraft bus that will carry the CubeSat to the International Space Station. This visit will take place in early November.

September 2014 – Everyone is really excited about the launch in April 2015. The students will have a day off school to watch the launch on Wallops Isand, Virginia.

June 2014 – STM students shared with Catholic Life TV how they intend to explore God’s Universe with their very own satellite.

June 2014 – Students are working on a new strategy for deploying the antenna using fishing line and the natural heat produced by a resistor.
