ISRO has completed the docking of satellites under its Space Docking Experiment - SpaDex mission. ISRO has released a video of successful docking on social media.

ISRO successfully conducts space-docking test under SpaDex mission

Indian Space Agency ISRO's twin SpaDeX satellites which were 500 meters apart and closing in on Wednesday night, have now drifted apart and are at a 13-fold distance, and are approximately 6.5 km away, as per private firms tracking the mission. Sharing their tracking data from the morning hours of January 9, Thursday, Indian private firm Digantara said that they tracked the SpaDeX A and B satellites as being 6.5 km apart. Likewise, Switzerland-based s2a systems tracked the twin satellites as they were 6.7 km apart.

<h2> Two postponed docking attempts</h2>
The SpaDeX satellites were meant to complete autonomous docking in the morning hours of Jan 9, Thursday. However, on Wednesday night as one of the twin satellites initiated the drift to move closer from 500m to 225m, the drift between satellites was found to be more than expected, therefore leading to temporary postponement. This is the second postponement of the docking. Earlier this week, the docking was postponed as ISRO wanted to perform a software test and on-ground simulation. &nbsp;

<h2> Why is space docking so complicated?</h2>
When a chaser spacecraft is approaching the target spacecraft, the relative velocity between the two(the difference in velocity between the two) and the distance between the two must be controlled very carefully. If the relative velocity is too high, the docking attempt can fail, causing damage or collisions. If it is too low, it may take too long to complete the approach, which could lead to fuel inefficiencies or mission delays.
When the spacecraft dock, their relative velocity must be near zero. This means that the two spacecraft must be moving at the same velocity and in the same direction at the time of docking to ensure a smooth mechanical connection without any impact forces. This requires careful coordination and manoeuvring, all done fully autonomously.
Initially the satellites were over 10kms apart from each other. Gradually, the satellites began to autonomously reduce the distance between themselves. The inter-satellite distance had been lowered to 5 km, 1.5 km, 500m.&nbsp;
On Wednesday night, one of the twin satellites had initiated the drift to move closer from 500m to 225m, and that's when the drift between satellites was found to be more than expected, therefore leading to temporary postponement with no new docking date announced so far.
WION had earlier reported that SpaDeX is ISRO's most complicated mission yet in orbit around Earth. ISRO's twin SpaDeX satellites being of small size(and carrying commensurate fuel) also add to the complexity of the mission. It is widely regarded that docking larger satellites with larger quantities of fuel is relatively simpler.
As this is India's maiden docking mission, ISRO is predominantly relying upon the natural drift of the satellites to bring them closer, which is why it is a time-consuming process. It must be noted that SpaDeX was launched on 30th December and docking was expected at least a week later. In contrast, large cargo-carrying or human-carrying spacecraft dock with the International Space Station eight hours after being launched into space. This is done by firing the on-board engines of the spacecraft and syncing up in close proximity with the space station, leading to docking.

While ISRO has assured that the satellites are safe, it will take a short while before ground-based antennas will be able to "see and speak" to the satellites. Typically, satellites that are closer to earth (SPADEX satellites are 470 km above earth) are only visible for a couple of minutes from each ground-based station, as the satellites move at speeds of over 28,000 kmph.

ISRO's SPADEX docking mission postponed for second time; satellites safe

ISRO's workhorse PSLV rocket roared to life from the first launchpad of Satish Dhawan Space Centre, Sriharikota, lighting up the night skies as it soared to space. 
Barely 15 minutes after launch, the vehicle ejected the twin <a href="https://www.wionews.com/videos/isro-pslv-c60-launches-spadex-for-critical-space-docking-experiment-launches-successfully">SPADEX</a> satellites into their designated orbit 475 km above the earth's surface. "PSLV has placed the satellites in the right orbit. Panels of the satellites have been deployed successfully," ISRO Chief Dr. S.Somanath confirmed in his post-launch address. 
We are hoping to achieve docking by the 7th January forenoon, said M. Sankaran, Director of ISRO's UR Rao Satellite Centre, the facility that designs and builds the Indian space agency's spacecraft. He added that the satellites need a week's time to be in an appropriate position with respect to the sun&nbsp;to harness solar power using their onboard solar panels. 
<h2>What is SPADEX? </h2>
SPADEX stands for Space Docking Experiment, and it is a crucial technological feat that would enable India's future space missions. India hopes to build an independent space station by the year 2035, and the first module (component) of this space station is meant to be launched in 2028. Space stations are built by autonomously assembling various modules while they circle the Earth. SPADEX is India's maiden attempt at space docking, which is&nbsp;the process of coupling two satellites into a single unified entity. India's Chandrayaan-3 Lunar sample return mission will also involve highly sophisticated space docking. So far, only the US, Russia, Europe, and China have mastered space docking technology.

<h2>Applications of space docking </h2>
Docking establishes a mechanical link between one orbiting spacecraft and another equally sized or larger orbiting body. When astronauts travel to the space station, the craft that carries them has to dock with the space station, following which the crew can move to the orbiting lab-cum-accommodation. Cargo is also delivered to the space station in a similar fashion. Likewise, docking can enable the transfer of fuel between two spacecrafts, thereby extending the life of the recipient craft. 
<h2>How will ISRO execute SPADEX?</h2>
The primary objective of the SPADEX mission is to develop and demonstrate the technology needed for rendezvous, docking, and undocking of two small spacecraft - SDX01, which is the Chaser, and SDX02, the Target. Each satellite weighs 220 kg, and will be hurled into a circular orbit that is 470 km above the earth's surface.

At the time of the ejection, the final stage of the PSLV rocket will be utilised to give a small relative velocity between the Target and Chaser spacecraft at the time of separation from the launch vehicle. Simply put, the target satellite will be travelling slightly faster than the chaser. This incremental velocity will allow the Target spacecraft to build a distance of 10-20 km with the Chaser.
Gradually, the satellites will autonomously reduce the distance between themselves by adjusting their respective velocities. From 20 km, the inter-satellite distance would be lowered to 5 km, 1.5 km, 500 m, 225 m, 15 m, and 3 m, ultimately leading to the docking of the two spacecraft. After successful docking and unification, electrical power transfer between the two satellites will be demonstrated. Electrical power transfer is crucial for carrying out in-space robotics, control of the unified spacecraft, etc. "Docking will be carried out between 6th January and 10th January," <a href="https://www.wionews.com/science/exclusive-indian-astronauts-us-training-to-go-on-for-three-months-750880">ISRO Chairman Dr. S.Somanath</a> had told WION. 
After the primary mission of docking is accomplished, the two satellites will then separate (undock) and start operating as two different satellites, operating their respective payloads for the expected mission life of up to two years.
ISRO Chairman Dr. S. Somanath told WION that the satellites could attempt more docking and undocking, depending on the mission requirements and the availability of fuel on both crafts. As small satellites weighing around 220 kg each, the SPADEX satellites carry very limited fuel&nbsp;when compared to their larger counterparts. 
<h2>Payloads being carried by SPADEX satellites</h2>
SDX01, the Chaser, carries a High-Resolution Camera (HRC) with photo and video capabilities. This is a miniature version of the surveillance camera developed by ISRO's Space Applications Centre (SAC).
SDX02, the Target, carries a Multi-Spectral Payload (MMX) used for natural resource monitoring and vegetation studies. It also carries a Radiation Monitor, which will measure radiation doses encountered in space, which will help suitably plan and execute India's homegrown Gaganyaan astronaut missions.
