REAL SPACE: THE MISSIONS


“The universe is probably littered with the one-planet graves of
cultures which made the sensible economic decision that there's
no good reason to go into space - each discovered, studied, and
remembered by the ones who made the irrational decision.”

― Randall Munroe

Join us, @DiscoSlelge, @HooHungLow and me in a journey trough the history of man's space exploration!!

 

This is a series about real space exploration missions complemented with their history, objectives and details about the boosters who launched them.

Missions from the past, present and future are planned, always trying to be accurate but without exhausting details, and also keeping  stock-alike aesthetics.

The TDRS Network

 

Introduction:

Not exactly an exploration mission, the Tracking and Data Realy Satellite network of communication satellites  brings connectivity to several key components for NASA and various US agencies.

Constituted by 10 operational spacecraft across 3 Generations, the TDRS Network operates in S, Ka and Ku bands supporting basic telemetry and data relay, high speed internet access and basic navigation.

Satellite Generations:

  • First Generation TDRS: models A to G - Launched by the Space Shuttle
  • Second Generation TDRS: models H to J - Launched by the Atlas IIA
  • Third Generation TDRS: models K to M - Launched by the Atlas V 401

 

The Missions:

TDRS-G (TDRS-7)

Launched by: Space Shuttle Atlantis  + IUS (inertial upper stage) on STS-70

Launch date: 13 July 1995

Launch site: KSC LC-39B

 

 

Discovery lifts off at 13:41:55 UTC

They will slowly separate before igniting the IUS first stage engine

About an hour later, IUS ignites, raising its payload to GTO (Geosynchronous Transfer Orbit)

TDRS-H (TDRS-8)

 

Launched by: Atlas IIA

Launch date: 30 June 2000

Launch site: KSC SLC-36A

Like all its predecessors before it, the Atlas IIA 1 and a 1/2 stage detaches leaving its main engine alone

Also, like a great part of the Atlas family, the centaur upper stage takes over making the payload orbit insertion

TDRS-K (TDRS-11)

 

Launched by: Atlas V 401

Launch date: 31 January 2013

Launch site: KSC SLC-41

 

No so different than the last one, so I'll only cover some differences.

Operation Paperclip: The German Connection

 

Introduction:

During World War II the V-2 rocket was amongst the most advanced weapons produced by Naz!-Germany. Hundreds of V-2 Rockets were launched against Allied targets. Near the end of the war the United States and Soviet Union rushed to confiscate and reverse engineer the Naz! technology as a means to produce even more sophisticated weaponry for wars to come. In order to stifle the efforts of the Soviet Union, the United States launched Operation Paperclip, a secret program that recruited German scientist and engineers, such as former SS-Sturmbannführer Wernher von Braun to work for the US Military. With the help of von Braun, the US captured 100 V-2 rockets to the recently established White Sands Missile Range. From 1946-1951 the US Army fired 67 V-2 rockets from the site. 

The Missions:

V-2/A4 Testing

Launched by: US confiscated V-2 Rockets

Launch date(s): 1946-1951

Launch site: Launch Complex 33, White Sands Missile Range, New Mexico, USA
