On January 30, 2024, SpaceX launched a private cargo spacecraft to the International Space Station (ISS). The launch took place at 12:07 PM EST from Cape Canaveral Space Force Station in Florida. The mission is known as NG-20, and it’s the 20th operational cargo delivery flight to the ISS.

The launch was carried out by a SpaceX Falcon 9 rocket, which is a reusable, two-stage rocket designed for transporting people and payloads into Earth orbit. The rocket launched Northrop Grumman’s 21st Cygnus cargo freighter

SpaceX has been delivering cargo to the International Space Station (ISS) since 2012. In May 2012, SpaceX’s Dragon spacecraft became the first commercial spacecraft to deliver cargo to the ISS. In 2020, SpaceX became the first private company to transport humans to the ISS. 

The Dragon is a family of spacecraft developed and produced by SpaceX. The first Dragon, also known as Dragon 1, flew 23 cargo missions to the ISS between 2010 and 2020

SpaceX’s first operational cargo mission to the International Space Station (ISS) was SpaceX CRS-1, also known as SpX-1. The mission was part of SpaceX’s Commercial Resupply Services (CRS-1) contract with NASA. 

The first SpaceX Dragon, also known as Dragon 1, flew 23 cargo missions to the ISS between 2010 and 2020. On May 25, 2012, NASA astronaut Don Pettit used the Canadarm2 to grapple the first SpaceX Dragon and berth it to the Harmony module

Dragon 1. Dragon 1 was the original Dragon iteration, providing cargo service to the ISS. It flew 23 missions between 2010 and 2020, when it was retired. On May 25, 2012, NASA astronaut Don Pettit operated the Canadarm2 to grapple the first SpaceX Dragon and berth it to the Harmony module

SpaceX’s SpaceX CRS-1 mission in 2012was the first operational commercial resupply mission to the International Space Station (ISS). Orbital Sciences’ Cygnus CRS Orb-1 mission in 2014 was the second

The first long-term residents of the International Space Station (ISS) arrived on November 2, 2000. Since then, the ISS has been continuously occupied for 23 years and 79 days. As of December 2023, 273 people from 21 countries have visited the ISS

The ISS became fully operational in May 2009 when it began hosting a six-person crew. Since August 2000, the ISS has been resupplied every three months with food, water, air, and equipment by Progress-M cargo vessels.

Originally SpaceX and Orbital ATK were awarded NASA’s Commercial Resupply Services contracts and SpaceX continues to fly its cargo Dragon spacecrafts on resupply runs to the ISS. Each company has a contract to send up cargo twice a year. Northrop Grumman acquired Orbital ATK in 2018

SpaceX also manufactures and operates the Falcon Heavy and Falcon 9 Full Thrust launch vehicles. The Falcon Heavy is one of the world’s most powerful operational rockets, capable of lifting 64 metric tons (141,000 lbs) to orbit

SpaceX is also developing the Starship, a two-stage super heavy lift launch vehicle. The Starship is intended to be fully reusable, with both stages recovered and reused after a mission. The Starship is the largest and most powerful rocket ever flown, and is designed to carry crew and cargo to Earth orbit, the Moon, Mars, and beyond

SpaceX CEO Elon Musk has said that the Falcon 1, 9, and Heavy rockets are named after the Millennium Falcon from the Star Wars franchise. Many of SpaceX’s products are named after birds of prey, including the Falcon rocket series and the Merlin engines used on the first stage of the rockets. 

Musk has also named other SpaceX systems and drones with creative names that have meaning behind them. For example, the barge ships “Just Read The Instructions” and “Of Course I Still Love You” are named after the sci-fi author Iain M

SpaceX rockets have several unique features:

  • Reusability The Falcon 9 is the world’s first orbital-class reusable rocket, which allows SpaceX to reuse the most expensive parts of the rocket. This reduces the cost of space access. 
  • Material The Starship rocket and its Super Heavy Booster will be made of 300-series stainless-steel instead of carbon fiber. 
  • Size The Falcon 9 is the world’s largest commercial rocket and one of the most reliable carriers. The latest versions can put 22,800 kg of payload into low Earth orbit. 
  • Mission SpaceX is the first private company to develop a liquid-propellant rocket that has reached orbit, and to send astronauts to the International Space Station. 
  • Philosophy SpaceX’s company philosophy is to fail fast, find problems, and fix them with the next rocket. This is different from the more traditional approach taken by organizations such as NASA

SpaceX’s Starship is the most powerful launch vehicle ever developed. It’s capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable

The Starship is also the largest and most powerful rocket ever built. It’s more than 120 meters tall and has a fueled mass of around 5,000 tonnes. 

The Falcon Heavy is also one of the most capable rockets flying, with more than 5 million pounds of thrust at liftoff. That’s about the same as 18 747 aircraft at full power

The SpaceX Starship rocket is made up of two parts: the Super Heavy booster and the Starship spacecraft. The Super Heavy booster is 233 feet tall and 30 feet wide, and contains 33 Raptor engines. The Starship spacecraft is 160 feet tall and 30 feet in diameter, and contains 6 Raptor engines

The Starship is designed to be fully reusable, including both the Super Heavy booster and the Starship spacecraft. The Starship uses methane and oxygen for fuel, which can be made on Mars. It also uses “hot staging”, which means the upper stage engines ignite while it’s still attached to the booster. This approach is commonly used in Russian rockets and could unlock greater power

The SpaceX Starship and Super Heavy are stacked onto their launch mount and loaded with fuel. The Starship quick disconnect (SQD) arm and booster quick disconnect (BQD) are used for this process. The SQD then retracts, and the 33 engines of Super Heavy ignite, causing the rocket to lift off

The Starship Super Heavy is a two-part system that consists of the 68-meter-long booster stage, called Super Heavy, and the Starship spacecraft. The Super Heavy is powered by 33 Raptor engines. 

During hot staging, Super Heavy shuts down all but three of its engines, while the second stage fires its engines before separating.

When stacked together, the SpaceX Starship and Super Heavy are 394 feet (120 meters) tall. This is nearly 100 feet taller than the Statue of Liberty and 31 feet taller than the Saturn V, the next-tallest rocket ever built

The Super Heavy is 233 feet (71 m) tall and 30 feet (9 m) wide. The Starship is 165 feet (50 m) tall and 30 feet in diameter. The Super Heavy’s 33 Raptor engines generate more than 16 million pounds of thrust, which is roughly twice that of the Saturn V.
