In science:

Abstract— The Atacama Large Millimeter Array (ALMA) will consist of up to 64 state-of-the-art sub-mm telescopes, subject to stringent performance specifications which will push the boundaries of the technology, and makes testing of antenna performance a likewise challenging task.
Study of the Dynamics of Large Reflector Antennas with Accelerometers
Although it may be possible to reduce the effect of the ramp with a pre-flash strategy similar to that adopted for the 8 µm IRAC array, a further defense against these challenges would seem to be a more comprehensive campaign of array characterization.
Spitzer/MIPS 24 micron Observations of HD 209458b: 3 eclipses, 2.5 transits, and a Phase Curve Corrupted by Instrumental Sensitivity Variations
Gravitational wave detection using space based detectors and Pulsar Timing Arrays bring with them the additional challenge of having to isolate individual signals that overlap one another in both time and frequency.
Gravitational Wave Astronomy: Needle in a Haystack
However, simulations of quantum magnetism allowing controlled, tunable interactions between spins localized on 2D and 3D lattices of more than a few 10’s of qubits have yet to be demonstrated, owing in part to the technical challenge of realizing large-scale qubit arrays.
Engineered 2D Ising interactions on a trapped-ion quantum simulator with hundreds of spins
HEMTs, and the improvements in sensitivity for deployments in space are even more impressive.) A challenge for future experiments based on HEMTs will be to build the large focal plane arrays that will be needed to achieve the sensitivity required to detect B mode polarization.

Consequently a challenge facing the community is how to fund the development of these expensive arrays.
Experimental CMB Status and Prospects: A Report from Snowmass 2001
Understanding their chemical composition and the chemical processes is in fact one of the major challenge for astrochemistry, although the next generation of telescopes (in particular ALMA, the Atacama Large Millimeter Array) is needed to put stringent constraints on the models.
Chemical processes in star forming regions
Their importance as probes of this inner CSE was realized soon after their first detection in the 1970s but early imaging studies faced difficult technical challenges (Moran et al. 1979; Genzel et al. 1979), primarily due to the low sensitivity of millimeter-wavelength VLBI arrays.
Stellar masers, circumstellar envelopes, and supernova remnants
Since each single array comprises tens or hundreds of thousands of measurements, the challenge is to find numerical summaries which can be used to make accurate quality calls.
Quality assessment for short oligonucleotide microarray data
Due to the scales and numbers in these arrays, active control of individual oscillators poses a number of challenging problems.
Synchronization by Reactive Coupling and Nonlinear Frequency Pulling
In the simulated B array observations (Figures 9 to 12) the challenge was to resolve the three sharp peaks near the core and as much of the jet morphology as possible.
